the result is that recorder record silence, no peak power, no avarage power.
i use xcode4 (ios inxcode4 is till 4.3, i have not downloaded the latest xcode)
why in ios5 doesn't work anymore?
is not compatible?
thanks

solved but don't know why it stopped working.
the code above was putted in a singleton class loaded and initialized once at start of the app.
seems that records only one voice power then stops (even if i have controlled that recording=true, metering enabled=true ecc...in logs)
now i have putted the same code in a method of the singleton class and called that method from the file of the screen "ingame" and works...
mmm.......any ideas why it happens?
